Why not put all the informations in the first post?  Interested worker would wonder what it is all about -the project, official website and ANN thread so they can view if they have already ideas on it. Applicants can advance the study before applying.
I don't have yet experience on managing slack and telegram channels but I joined several campaigns before. I want to ask if posting news and articles would be created by ours or you would just provide the links to be shared to the subscribers? Thank you.
